Toronto swimming beach water quality tracker: Updated daily

Check out water-quality data at 10 swimming beaches around Toronto, from June through Labour Day.

During swimming season, Toronto maintains 10 supervised beaches that “meet high standards for water quality, environmental management, environmental education, and safety.”

The beaches are spread out along the shore of Lake Ontario and across the Toronto Islands, and from Sat., June 3, through Labour Day each will be staffed with lifeguards.

Is it safe to swim in Toronto?

Yes, with standard caveats. It’s best to avoid swimming in lakes for 48 hours after heavy rainfall due to potentially elevated amounts of bacteria in the water, and Toronto beaches are no exception.

Conditions will also vary depending on the day and location, so the city conducts daily tests for E.coli bacteria at each of its swimming beaches. Staff check to see whether levels are within the standard of 100 E.coli per 100 mL of water, then make the results available through open data.

We’re ingesting that data to help you better plan your swimming excursions in the city. See below or check the map for the latest conditions.
